Re: [PATCH 1/4] SecurityPkg: enable TPM components to build for ARM and AARCH64

["Cohen, Eugene" <eugene@hp.com>]

Jiewen,

1 and 2 - okay, no problem, working on it.

3 - we are developing the SPI TPM support as we speak.  Our SPI controller is proprietary so there's no value in trying to share that driver.  Our internal SPI driver currently does not support the PI spec SPI_IO_PROTOCOL but are looking at adopting it - if so then we could contribute the TpmIoLibSpi instance which would connect the TPM stack to the SPI_IO_PROTOCOL.  Is this what you wanted or is there something more specific you were looking for?

Thanks,

Eugene
